Tongue Tie

Dear Doctor, My daughter has just had a little girl who apparently has 'tongue tie' and as a result she is struggling with the feeding. I believe there is a surgical procedure which can be carried out. Is this really necessary as I have come across different opinions in Medical literature. Is it a dangerous procedure and who should we consult at this stage . The baby is 2 days old and how long can one wait? Many Thanks, Concerned GRandmother
